Paper Abstract

The accurate measurement of objects such as turbine blades is of great importance in determining ''as built'' dimensions. From these data further information can be derived which allows assessment of: balance damage and adherence to design plans. In this paper three techniques for the reconstruction of 3-D shape are compared and contrasted. Examples of data collected from: Photogrammetry Optical Triangulation and Moire are presented. The method chosen for a particular task will depend on the qualities of each technique sufficient information is given to assist in an appropriate selection.
